Minus the ACLs, we're dropping those in the next release.

That would be neat.

I'm not sure what you're trying to accomplish here. Why would clients  
subscribe to a specific outlet? And why would we want to switch off an  
outlet early?

We already have 'upssched' to shutdown clients early, so the only load  
saving that would benefit from shutdown through the outlet switches  
are 'dumb' devices that don't run NUT client software or NUT clients  
that somehow are no longer responsive. In both cases, they will be  
shutdown 'hard' anyway and as far as I can see there is little you can  
do about it.

Best regards, Arjen
